• Decreasing the Hue value moves
clockwise around the color wheel to
select a base color.
a)
Use the Cntrl knob to select Reject.
b)
Use the Value knob to include or reject hues
adjacent to the base color.
• Increasing the Reject value decreases
the amount of adjacent hues that are
included in the foreground.
• Decreasing the Reject value increases
the amount of adjacent hues that are
included in the foreground.
11.
Adjust the amount of background color that is
spilling over into the foreground as follows
(green color cast on the foreground from a green
screen for example):
a)
Use the Type knob to select Spill.
b)
Use the Value knob to remove any color cast
onto the foreground.
• Increasing the Range value causes
more of the foreground colors to be
corrected for background color spill.
• Decreasing the Range value causes
fewer of the foreground colors to be
corrected for background color spill.
12.
Press NEXT.
13.
Use the Mask knob to apply a mask to the key.
Chroma Key Advanced Mode
An UltraChrome chroma key, in advanced mode, breaks
the image into five elements which determine, or partially
determine, which part of the image is keyed out, or
removed.
• Background — Background elements are those
pixels in the source video that are the same color
as the one you chose to key out. Note that the
Shadow and translucent areas (see below) are
completely contained within the Background area.
• Shadow — Shadow elements are those pixels in
the source video with colors that are within the
Background range, but with lower luminance
values, depending on the shadow range. You
modify the Shadow range to cover darker areas of
the background (e.g. where the foreground is
casting a shadow on the background screen).
• Translucency — Translucent elements are those
pixels in the source video that are in the
Background range, but with higher luminance
values than the Shadow range. You can control the
upper-end of the Translucency range by setting a
wider hue-range to constrain the area. You can also
control the transparency of the Translucent area.
• Transition — Transition elements are those pixels
in the source video with colors that are not within
any of the previous three ranges and are also not
considered part of the Foreground area. These are
typically the pixels near the edge of the foreground,
where it blends into the background.
• Foreground — Foreground elements are those
pixels that are not within the Background, Shadow,
Translucency, or Transition ranges. This is the area
with colors that will not be keyed out and will
remain solid.
The remaining three adjustments that can be made to an
Advanced UltraChrome chroma key allow you to adjust
spill suppression, edge softness and luminance.
• Spill Suppress — Spill Suppression elements are
those pixels in the Foreground that have a
noticeable tint of the Background color. This
typically occurs around the edge of the foreground
subject as glow from the background blue-screen
or green-screen “spills” onto them.
• Edge Softness — Edge Softness lets you apply
varying degrees of softening to the Foreground
edges to help it blend in with the underlying
background image that it is being keyed over.
• Luminance — Luminance allows you to control
the overall brightness of Shadow, Translucency,
and Transition areas as well as partial reflections
to more closely match the Foreground brightness.
To Set Up a Chroma Key in Advanced Mode
The UltraChrome chroma key tries to automatically
adjust for the scene you are trying to chroma key. For
the best results, initialize the key first, and then identify
the areas where you need to adjust the key.
1.
Select the keyer that you want to set up a basic
Chroma Key.
2.
Select the video signal on the key bus that you
want to use for the key.
3.
Press CHR KEY.
4.
Use the Mode knob to select Adv.
5.
Use the Color knob to select the color you want
to key out.
6.
